Radio resource management for full-duplex operation of integrated access and backhaul for 5g or other next generation network

ABSTRACT

Integrate access and backhaul (IAB) nodes can multiplex access and backhaul links in time, frequency, or space, which includes the transmission of signals and/or channels utilized as part of initial access and measurements used for radio resource management (RRM). The same physical layer signals and channels used for these purposes by access a user equipment device can be reused for performing similar procedures at the IAB node. Consequently, the IAB node can leverage various muting patterns to employ the use of half-duplex and full-duplex synchronization signal block radio resource management such that mobile terminal functionality and distributed unit functionality of the IAB node can receive and transmit signals simultaneously.

RELATED APPLICATION

The subject patent application is a continuation of, and claims priority to, U.S. patent application Ser. No. 16/874,220, filed May 14, 2020, and entitled “RADIO RESOURCE MANAGEMENT FOR FULL-DUPLEX OPERATION OF INTEGRATED ACCESS AND BACKHAUL FOR 5G OR OTHER NEXT GENERATION NETWORK,” the entirety of which priority application is hereby incorporated by reference herein.

TECHNICAL FIELD

This disclosure relates generally to facilitating radio resource management. For example, this disclosure relates to facilitating radio resource management for full-duplex operation of integrated access and backhaul for a 5G, or other next generation network, air interface.

BACKGROUND

5^(th) generation (5G) wireless systems represent a next major phase of mobile telecommunications standards beyond the current telecommunications standards of 4^(th) generation (4G). Rather than faster peak Internet connection speeds, 5G planning aims at higher capacity than current 4G, allowing a higher number of mobile broadband users per area unit, and allowing consumption of higher or unlimited data quantities. This would enable a large portion of the population to stream high-definition media many hours per day with their mobile devices, when out of reach of wireless fidelity hotspots. 5G research and development also aims at improved support of machine-to-machine communication, also known as the Internet of things, aiming at lower cost, lower battery consumption, and lower latency than 4G equipment.

The above-described background relating to facilitating radio resource management for full-duplex operation of integrated access and backhaul is merely intended to provide a contextual overview of some current issues, and is not intended to be exhaustive. Other contextual information may become further apparent upon review of the following detailed description.

It should be noted that although various aspects and embodiments have been described herein in the context of 5G, Universal Mobile Telecommunications System (UMTS), and/or Long Term Evolution (LTE), or other next generation networks, the disclosed aspects are not limited to 5G, a UMTS implementation, and/or an LTE implementation as the techniques can also be applied in 3G, 4G or LTE systems. For example, aspects or features of the disclosed embodiments can be exploited in substantially any wireless communication technology. Such wireless communication technologies can include UMTS, Code Division Multiple Access (CDMA), Wi-Fi, Worldwide Interoperability for Microwave Access (WiMAX), General Packet Radio Service (GPRS), Enhanced GPRS, Third Generation Partnership Project (3GPP), LTE, Third Generation Partnership Project 2 (3GPP2) Ultra Mobile Broadband (UMB), High Speed Packet Access (HSPA), Evolved High Speed Packet Access (HSPA+), High-Speed Downlink Packet Access (HSDPA), High-Speed Uplink Packet Access (HSUPA), Zigbee, or another IEEE 802.12 technology. Additionally, substantially all aspects disclosed herein can be exploited in legacy telecommunication technologies.

Described herein are systems, methods, articles of manufacture, and other embodiments or implementations that can facilitate radio resource management for full-duplex operation of integrated access and backhaul for a 5G network. Facilitating radio resource management for full-duplex operation of integrated access and backhaul for a 5G network can be implemented in connection with any type of device with a connection to the communications network (e.g., a mobile handset, a computer, a handheld device, etc.) any Internet of things (IOT) device (e.g., toaster, coffee maker, blinds, music players, speakers, etc.), and/or any connected vehicles (cars, airplanes, space rockets, and/or other at least partially automated vehicles (e.g., drones)). In some embodiments the non-limiting term user equipment (UE) is used. It can refer to any type of wireless device that communicates with a radio network node in a cellular or mobile communication system. Examples of UE are target device, device to device (D2D) UE, machine type UE or UE capable of machine to machine (M2M) communication, PDA, Tablet, mobile terminals, smart phone, laptop embedded equipped (LEE), laptop mounted equipment (LME), USB dongles etc. The embodiments are applicable to single carrier as well as to multicarrier (MC) or carrier aggregation (CA) operation of the UE. The term carrier aggregation (CA) is also called (e.g., interchangeably called) “multi-carrier system”, “multi-cell operation”, “multi-carrier operation”, “multi-carrier” transmission and/or reception.

In some embodiments the non-limiting term radio network node or simply network node is used. It can refer to any type of network node that serves UE is connected to other network nodes or network elements or any radio node from where UE receives a signal. Examples of radio network nodes are Node B, base station (BS), multi-standard radio (MSR) node such as MSR BS, eNode B, network controller, radio network controller (RNC), base station controller (BSC), relay, donor node controlling relay, base transceiver station (BTS), access point (AP), transmission points, transmission nodes, RRU, RRH, nodes in distributed antenna system (DAS) etc.

Cloud radio access networks (RAN) can enable the implementation of concepts such as software-defined network (SDN) and network function virtualization (NFV) in 5G networks. This disclosure can facilitate a generic channel state information framework design for a 5G network. Certain embodiments of this disclosure can include an SDN controller that can control routing of traffic within the network and between the network and traffic destinations. The SDN controller can be merged with the 5G network architecture to enable service deliveries via open application programming interfaces (“APIs”) and move the network core towards an all internet protocol (“IP”), cloud based, and software driven telecommunications network. The SDN controller can work with, or take the place of policy and charging rules function (“PCRF”) network elements so that policies such as quality of service and traffic management and routing can be synchronized and managed end to end.

5G, also called new radio (NR) access, networks can include the following: data rates of several tens of megabits per second supported for tens of thousands of users; 1 gigabit per second can be offered simultaneously to tens of workers on the same office floor; several hundreds of thousands of simultaneous connections can be supported for massive sensor deployments; spectral efficiency can be enhanced compared to 4G; improved coverage; enhanced signaling efficiency; and reduced latency compared to LTE. In multicarrier systems such as OFDM, each subcarrier can occupy bandwidth (e.g., subcarrier spacing). If the carriers use the same bandwidth spacing, then it can be considered a single numerology. However, if the carriers occupy different bandwidth and/or spacing, then it can be considered a multiple numerology.

Downlink reference signals are predefined signals occupying specific resource elements within a downlink time-frequency grid. There are several types of downlink reference signals that can be transmitted in different ways and used for different purposes by a receiving terminal. Channel state information reference signals (CSI-RS) can be used by terminals to acquire channel-state information (CSI) and beam specific information (e.g., beam reference signal received power). In 5G, CSI-RS can be user equipment (UE) specific so it can have a significantly lower time/frequency density. Demodulation reference signals (DM-RS), also sometimes referred to as UE-specific reference signals, can be used by terminals for channel estimation of data channels. The label “UE-specific” relates to the demodulation reference signal being intended for channel estimation by a single terminal. The demodulation reference signal can then be transmitted within the resource blocks assigned for data traffic channel transmission to that terminal. Other than the aforementioned reference signals, there are other reference signals, namely multi-cast broadcast single frequency network (MBSFN) and positioning reference signals that can be used for various purposes.

CSI-RS signal transmission is important for estimating the CSI. Although resources implicated for CSI-RS can be small, when multiple numerologies are deployed within the same OFDM bandwidth, using a conventional approach (as in LTE), estimating the CSI can include a CSI-RS resource grid for every numerology. Therefore, time-frequency resources for CSI-RS can be high and occupy a lot of bandwidth, thereby reducing the number of resources for data transmission. Therefore, significant loss in data throughput can limit the system capacity. Hence, a solution is desirable for efficient use of CSI-RS resources for serving all numerologies.

Integrated access and backhaul (IAB) nodes can multiplex the access and backhaul links in time, frequency, or space (e.g., beam-based operation) which includes the transmission of signals/channels utilized as part of initial access and measurements used for radio resource management. The same physical layer signals and channels used for these purposes by access UEs can be reused for performing similar procedures at the IAB node. The examples in this section are based on the utilization of synchronization signal blocks (SSB), but can equally apply to CSI-RS resources used for radio resource management (RRM).

In yet another embodiment, the hybrid full-duplex plus half-duplex SSB patterns can be preconfigured or fixed in the specification. IAB nodes can indicate to the network which pattern(s) they support based on their capability, and the network can select from a subset of possible full-duplex only, half-duplex only, and hybrid full-duplex plus half-duplex SSB patterns when performing the initial RRM configuration for the network. The network can then send patterns to the IAB node.

In another alternative, the ratio of full-duplex supporting windows and half-duplex windows can be configurable by the network and indicated to the IAB node DUs and IAB node MTs via higher layer signaling. In one example, an indication can comprise a bitmap indicating which windows are active for SSB transmission and/or reception over a given period of time (e.g., 160 ms or 640 ms). In another example, the indication can comprise a periodicity of the windows (e.g., 20 ms, 40 ms, or 80 ms), a first offset for the window (e.g., 0 ms for all patterns in FIG. 7 below) and a second offset (e.g., 0 ms for pattern 1, 5 ms for pattern 2, and 10 ms for pattern 3 in FIG. 7 below) which can be used to indicate the shifts in the windows for different patterns based on whether full-duplex or half-duplex is supported in the given window period. The configuration can be adapted semi-statically based on the network topology changes for example.

In another embodiment, the network can configure resources for data transmission/reception for IAB nodes in addition to resources for RRM. Two types of resources, “hard” and “soft” resources, can be configured for the data resources, where hard resources can only be used by the DU, while soft resources can be flexibly shared between the DU and MT based on traffic or interference considerations. Resources for RRM can be fixed to only be considered as hard resources when overlapping with the data resources due to the half-duplex constraint. However, if an IAB node supports full-duplex operation, this constraint may not be utilized since both the DU and MT can be active in a resource without a negative impact to either the DU or MT transmission/reception. As a result, a new rule can be applied for IAB nodes, which support full-duplex operation, enabling both hard and soft resources to be configured when overlapping with resources configured for the initial access/RRM.

In one embodiment, described herein is a method comprising initiating, by an integrated access backhaul device comprising a processor, a full-duplex operation to decrease a transmission latency. The method can comprise facilitating, by the integrated access backhaul device, transmitting a first synchronization signal block via a distributed unit functionality of the integrated access backhaul device during a time slot. Additionally, the method can comprise facilitating, by the integrated access backhaul device, receiving a second synchronization signal block via a mobile termination functionality of the integrated access backhaul device during the time slot.

According to another embodiment, a system can facilitate initiating a full-duplex operation via distributed unit function of the integrated access backhaul device. The system operations can comprise initiating a full-duplex operation via mobile termination function of the integrated access backhaul device. Additionally, the system operations can comprise transmitting a first synchronization signal block via the distributed unit function during a time slot. Furthermore, the system operations can comprise receiving a second synchronization signal block via the mobile termination function of the integrated access backhaul device during the time slot.

According to yet another embodiment, described herein is a machine-readable medium that can perform the operations comprising facilitating initiating a full-duplex operation via a distributed unit function of an integrated access backhaul device. The machine-readable medium can perform the operations comprising facilitating initiating a full-duplex operation via a mobile termination function of the integrated access backhaul device. Furthermore, the machine-readable medium can perform the operations comprising facilitating transmitting a first synchronization signal block via a distributed unit functionality of an integrated access backhaul device during a first time slot. Additionally, the machine-readable medium can perform the operations comprising facilitating receiving a second synchronization signal block via a mobile termination functionality of the integrated access backhaul device during a second time slot, wherein the first time slot and the second time slot are a same time slot.

These and other embodiments or implementations are described in more detail below with reference to the drawings.

Referring now to FIG. 1, illustrated is an example wireless communication system 100 in accordance with various aspects and embodiments of the subject disclosure. In one or more embodiments, system 100 can include one or more user equipment UEs 102. The non-limiting term user equipment can refer to any type of device that can communicate with a network node in a cellular or mobile communication system. A UE can have one or more antenna panels having vertical and horizontal elements. Examples of a UE include a target device, device to device (D2D) UE, machine type UE or UE capable of machine to machine (M2M) communications, personal digital assistant (PDA), tablet, mobile terminals, smart phone, laptop mounted equipment (LME), universal serial bus (USB) dongles enabled for mobile communications, a computer having mobile capabilities, a mobile device such as cellular phone, a laptop having laptop embedded equipment (LEE, such as a mobile broadband adapter), a tablet computer having a mobile broadband adapter, a wearable device, a virtual reality (VR) device, a heads-up display (HUD) device, a smart car, a machine-type communication (MTC) device, and the like. User equipment UE 102 can also include IOT devices that communicate wirelessly.

In various embodiments, system 100 is or includes a wireless communication network serviced by one or more wireless communication network providers. In example embodiments, a UE 102 can be communicatively coupled to the wireless communication network via a network node 104. The network node (e.g., network node device) can communicate with user equipment (UE), thus providing connectivity between the UE and the wider cellular network. The UE 102 can send transmission type recommendation data to the network node 104. The transmission type recommendation data can include a recommendation to transmit data via a closed loop MIMO mode and/or a rank-1 precoder mode.

A network node can have a cabinet and other protected enclosures, an antenna mast, and multiple antennas for performing various transmission operations (e.g., MIMO operations). Network nodes can serve several cells, also called sectors, depending on the configuration and type of antenna. In example embodiments, the UE 102 can send and/or receive communication data via a wireless link to the network node 104. The dashed arrow lines from the network node 104 to the UE 102 represent downlink (DL) communications and the solid arrow lines from the UE 102 to the network nodes 104 represents an uplink (UL) communication.

System 100 can further include one or more communication service provider networks 106 that facilitate providing wireless communication services to various UEs, including UE 102, via the network node 104 and/or various additional network devices (not shown) included in the one or more communication service provider networks 106. The one or more communication service provider networks 106 can include various types of disparate networks, including but not limited to: cellular networks, femto networks, picocell networks, microcell networks, internet protocol (IP) networks Wi-Fi service networks, broadband service network, enterprise networks, cloud based networks, and the like. For example, in at least one implementation, system 100 can be or include a large scale wireless communication network that spans various geographic areas. According to this implementation, the one or more communication service provider networks 106 can be or include the wireless communication network and/or various additional devices and components of the wireless communication network (e.g., additional network devices and cell, additional UEs, network server devices, etc.). The network node 104 can be connected to the one or more communication service provider networks 106 via one or more backhaul links 108. For example, the one or more backhaul links 108 can include wired link components, such as a T1/E1 phone line, a digital subscriber line (DSL) (e.g., either synchronous or asynchronous), an asymmetric DSL (ADSL), an optical fiber backbone, a coaxial cable, and the like. The one or more backhaul links 108 can also include wireless link components, such as but not limited to, line-of-sight (LOS) or non-LOS links which can include terrestrial air-interfaces or deep space links (e.g., satellite communication links for navigation).

Wireless communication system 100 can employ various cellular systems, technologies, and modulation modes to facilitate wireless radio communications between devices (e.g., the UE 102 and the network node 104). While example embodiments might be described for 5G new radio (NR) systems, the embodiments can be applicable to any radio access technology (RAT) or multi-RAT system where the UE operates using multiple carriers e.g., LTE FDD/TDD, GSM/GERAN, CDMA2000 etc.

For example, system 100 can operate in accordance with global system for mobile communications (GSM), universal mobile telecommunications service (UMTS), long term evolution (LTE), LTE frequency division duplexing (LTE FDD, LTE time division duplexing (TDD), high speed packet access (HSPA), code division multiple access (CDMA), wideband CDMA (WCMDA), CDMA2000, time division multiple access (TDMA), frequency division multiple access (FDMA), multi-carrier code division multiple access (MC-CDMA), single-carrier code division multiple access (SC-CDMA), single-carrier FDMA (SC-FDMA), orthogonal frequency division multiplexing (OFDM), discrete Fourier transform spread OFDM (DFT-spread OFDM) single carrier FDMA (SC-FDMA), Filter bank based multi-carrier (FBMC), zero tail DFT-spread-OFDM (ZT DFT-s-OFDM), generalized frequency division multiplexing (GFDM), fixed mobile convergence (FMC), universal fixed mobile convergence (UFMC), unique word OFDM (UW-OFDM), unique word DFT-spread OFDM (UW DFT-Spread-OFDM), cyclic prefix OFDM CP-OFDM, resource-block-filtered OFDM, Wi Fi, WLAN, WiMax, and the like. However, various features and functionalities of system 100 are particularly described wherein the devices (e.g., the UEs 102 and the network device 104) of system 100 are configured to communicate wireless signals using one or more multi carrier modulation schemes, wherein data symbols can be transmitted simultaneously over multiple frequency subcarriers (e.g., OFDM, CP-OFDM, DFT-spread OFMD, UFMC, FMBC, etc.). The embodiments are applicable to single carrier as well as to multicarrier (MC) or carrier aggregation (CA) operation of the UE. The term carrier aggregation (CA) is also called (e.g., interchangeably called) “multi-carrier system”, “multi-cell operation”, “multi-carrier operation”, “multi-carrier” transmission and/or reception. Note that some embodiments are also applicable for Multi RAB (radio bearers) on some carriers (that is data plus speech is simultaneously scheduled).

In various embodiments, system 100 can be configured to provide and employ 5G wireless networking features and functionalities. 5G wireless communication networks are expected to fulfill the demand of exponentially increasing data traffic and to allow people and machines to enjoy gigabit data rates with virtually zero latency. Compared to 4G, 5G supports more diverse traffic scenarios. For example, in addition to the various types of data communication between conventional UEs (e.g., phones, smartphones, tablets, PCs, televisions, Internet enabled televisions, etc.) supported by 4G networks, 5G networks can be employed to support data communication between smart cars in association with driverless car environments, as well as machine type communications (MTCs). Considering the drastic different communication demands of these different traffic scenarios, the ability to dynamically configure waveform parameters based on traffic scenarios while retaining the benefits of multi carrier modulation schemes (e.g., OFDM and related schemes) can provide a significant contribution to the high speed/capacity and low latency demands of 5G networks. With waveforms that split the bandwidth into several sub-bands, different types of services can be accommodated in different sub-bands with the most suitable waveform and numerology, leading to an improved spectrum utilization for 5G networks.

To meet the demand for data centric applications, features of proposed 5G networks may include: increased peak bit rate (e.g., 20 Gbps), larger data volume per unit area (e.g., high system spectral efficiency—for example about 3.5 times that of spectral efficiency of long term evolution (LTE) systems), high capacity that allows more device connectivity both concurrently and instantaneously, lower battery/power consumption (which reduces energy and consumption costs), better connectivity regardless of the geographic region in which a user is located, a larger numbers of devices, lower infrastructural development costs, and higher reliability of the communications. Thus, 5G networks may allow for: data rates of several tens of megabits per second should be supported for tens of thousands of users, 1 gigabit per second to be offered simultaneously to tens of workers on the same office floor, for example; several hundreds of thousands of simultaneous connections to be supported for massive sensor deployments; improved coverage, enhanced signaling efficiency; reduced latency compared to LTE.

The upcoming 5G access network may utilize higher frequencies (e.g., >6 GHz) to aid in increasing capacity. Currently, much of the millimeter wave (mmWave) spectrum, the band of spectrum between 30 gigahertz (Ghz) and 300 Ghz is underutilized. The millimeter waves have shorter wavelengths that range from 10 millimeters to 1 millimeter, and these mmWave signals experience severe path loss, penetration loss, and fading. However, the shorter wavelength at mmWave frequencies also allows more antennas to be packed in the same physical dimension, which allows for large-scale spatial multiplexing and highly directional beamforming.

Performance can be improved if both the transmitter and the receiver are equipped with multiple antennas. Multi-antenna techniques can significantly increase the data rates and reliability of a wireless communication system. The use of multiple input multiple output (MIMO) techniques, which was introduced in the third-generation partnership project (3GPP) and has been in use (including with LTE), is a multi-antenna technique that can improve the spectral efficiency of transmissions, thereby significantly boosting the overall data carrying capacity of wireless systems. The use of multiple-input multiple-output (MIMO) techniques can improve mmWave communications, and has been widely recognized a potentially important component for access networks operating in higher frequencies. MIMO can be used for achieving diversity gain, spatial multiplexing gain and beamforming gain. For these reasons, MIMO systems are an important part of the 3rd and 4th generation wireless systems, and are planned for use in 5G systems.

Referring now to FIG. 2, illustrated is an example schematic system block diagram of an integrated access backhaul (IAB) node 200 protocol stack according to one or more embodiments. The IAB node 200 can receive relay links (Ur) in the same manner that a UE receives and processes relay links. For example, the data traffic from the MT function 204 can transition up to the adaption layer 208 and then transition down to the DU function 206 of the IAB node 200. From there the data can be sent to another user or to another backhaul node if there are additional hops. With reference to FIG. 3, The IAB node 200 protocol stack can be between a donor distributed unit 306 and a relay distributed unit 308. An IAB control interface 202 can be introduced because the UE function 204 can be configured by the network and typically uses RRC signaling to for the configuration. However, the gNode B function 206 (relay distributed unit 308) can be controlled by the F1/OAM. Thus, a separate protocol stack can be leveraged for the gNode B function 426 and the IAB control interface 202 can connect the UE function 424 to the gNode B function 206 to can coordinate radio resources.

Referring now to FIG. 3, illustrated is an example schematic system block diagram of integrated access and backhaul links according to one or more embodiments. For example, the network 300, as represented in FIG. 3 with integrated access and backhaul links, can allow a relay node to multiplex access and backhaul links in time, frequency, and/or space (e.g., beam-based operation). Thus, FIG. 3 illustrates a generic IAB set-up comprising a core network 302, a centralized unit 304, a donor distributed unit 306, a relay distributed unit 308, and UEs 102 ₁, 102 ₂, 102 ₃. The donor distributed unit 306 (e.g., access point) can have a wired backhaul with a protocol stack and can relay the user traffic for the UEs 102 ₁, 102 ₂, 102 ₃ across the IAB and backhaul link. Then the relay distributed unit 308 can take the backhaul link and convert it into different strains for the connected UEs 102 ₁, 102 ₂, 102 ₃. Although FIG. 3 depicts a single hop (e.g., over the air), it should be noted that multiple backhaul hops can occur in other embodiments.

The relays can have the same type of distributed unit structure that the gNode B has. For 5G, the protocol stack can be split, where some of the stack is centralized. For example, the PDCP layer and above can be at the centralized unit 304, but in a real time application part of the protocol stack, the RLC, the MAC, and the PHY can be co-located with the base station wherein the system can comprise an F1 interface. In order to add relaying, the F1 interface can be wireless so that the same structure of the donor distributed unit 306 can be kept.

Referring now to FIG. 4, illustrated is an example schematic system block diagram of a half-duplex and full-duplex frame structure according to one or more embodiments.

The half-duplex constraint and the multi-hop topology of IAB, results in a staggered frame structure 400 as depicted in FIG. 4. One major advantage of a full-duplex IAB structure 402 is decreased latency. For example, when the donor DU (hop 0) sends DL transmissions to the IAB node 200 MT function 204 of hop order 1, said IAB node is receiving, hence it can schedule access UEs or child IAB nodes in the DL or UL. Alternatively, an IAB node MT function 204 of hop order 2 can transmit to the first order IAB node DU function 206 when the latter is receiving from the donor.

In addition to the ability to optimize the frame structure compared to Half-Duplex IAB nodes, the ability for IAB nodes 200 to perform radio resource measurement (RRM) functions for topology adaptation and backhaul link monitoring can be simplified in case of full-duplex operation and can reduce the overall overhead of the transmission and reception of measurement reference signals such as synchronization signal blocks (SSB).

Referring now to FIG. 5 illustrates an example schematic system block diagram of a half-duplex synchronization signal block radio resource management configuration 500 according to one or more embodiments.

Because IAB nodes 200 can comprise both DU functionality and MT functionality, this implies that the IAB node DU function 206 can transmit signals and channels used for initial access/RRM as well as receive reports from connected devices which may be both access UEs and higher order IAB nodes. As a result, while the same physical signals can be used for both UEs 102 and IAB nodes 200, different configurations of the resources and/or transmission period(s) of the signals used for RRM for access UEs 102 and IAB nodes 200 can be required or requested, and the parameters configuring RRM operation at the IAB node 200 DU function 206 can consider the half-duplex constraint imposed by the MT function 204 and can also take into account hop order and other topology/route management functionalities as shown in FIG. 5 where three orthogonal patterns are configured to allow IAB nodes to transmit and measure SSBs in different 5 ms windows with a periodicity of 20 ms.

Referring now to FIG. 6, illustrated is an example schematic system block diagram of a full-duplex synchronization signal block radio resource management configuration 600 according to one or more embodiments.

In another embodiment, if the IAB node 200 can supports a full-duplex operation, the SSB patterns can be fully overlapped, since in the same time slot as the IAB node DU 206 is transmitting an SSB, the co-located IAB node MT 204 can be receiving SSBs transmitted by other IAB nodes.

Referring now to FIG. 7, illustrated is an example schematic system block diagram of a hybrid synchronization signal block radio resource management configuration 700 according to one or more embodiments.

As depicted in FIG. 7, full-duplex and half-duplex operations can be supported for IAB node 200 RRM. This is beneficial in the case where the network is deployed with various types of IAB nodes with different physical layer and higher layer capabilities. As a result, while the half-duplex pattern in FIG. 5 can be used as the default pattern, it can result in significant overhead, especially if a large number of IAB nodes are capable of full duplex operation. FIG. 7 illustrates a hybrid pattern that can enable certain SSB transmission/reception windows to be aligned for full-duplex operation, while other windows are kept orthogonal for half-duplex operation.

Referring now to FIG. 8, illustrated is an example flow diagram for a method for facilitating radio resource management for full-duplex operation of integrated access and backhaul for a 5G network according to one or more embodiments.

At element 800, the method can comprise initiating, by an integrated access backhaul device comprising a processor, a full-duplex operation to decrease a transmission latency. At element 802, the method can comprise facilitating, by the integrated access backhaul device, transmitting a first synchronization signal block via a distributed unit functionality of the integrated access backhaul device during a time slot. Additionally, at element 804, the method can comprise facilitating, by the integrated access backhaul device, receiving a second synchronization signal block via a mobile termination functionality of the integrated access backhaul device during the time slot.

At element 902, the system operations can comprise initiating a full-duplex operation via mobile termination function of the integrated access backhaul device. Additionally, at element 904, the system operations can comprise transmitting a first synchronization signal block via the distributed unit function during a time slot. Furthermore, at element 906, the system operations can comprise receiving a second synchronization signal block via the mobile termination function of the integrated access backhaul device during the time slot.

At element 1002, the machine-readable medium can perform the operations comprising facilitating initiating a full-duplex operation via a mobile termination function of the integrated access backhaul device. Furthermore, at element 1004, the machine-readable medium can perform the operations comprising facilitating transmitting a first synchronization signal block via a distributed unit functionality of an integrated access backhaul device during a first time slot. Additionally, at element 1006, the machine-readable medium can perform the operations comprising facilitating receiving a second synchronization signal block via a mobile termination functionality of the integrated access backhaul device during a second time slot, wherein the first time slot and the second time slot are a same time slot.

A communications component 1110 interfaces to the processor 1102 to facilitate wired/wireless communication with external systems, e.g., cellular networks, VoIP networks, and so on. Here, the communications component 1110 can also include a suitable cellular transceiver 1111 (e.g., a GSM transceiver) and/or an unlicensed transceiver 1113 (e.g., Wi-Fi, WiMax) for corresponding signal communications. The handset 1100 can be a device such as a cellular telephone, a PDA with mobile communications capabilities, and messaging-centric devices. The communications component 1110 also facilitates communications reception from terrestrial radio networks (e.g., broadcast), digital satellite radio networks, and Internet-based radio services networks.

The handset 1100 includes a display 1112 for displaying text, images, video, telephony functions (e.g., a Caller ID function), setup functions, and for user input.

However, it is to be appreciated that the SIM card 1120 can be manufactured into the handset 1100, and updated by downloading data and software.

The handset 1100 can process IP data traffic through the communication component 1110 to accommodate IP traffic from an IP network such as, for example, the Internet, a corporate intranet, a home network, a person area network, etc., through an ISP or broadband cable provider. Thus, VoIP traffic can be utilized by the handset 1100 and IP-based multimedia content can be received in either an encoded or decoded format.

A video processing component 1122 (e.g., a camera) can be provided for decoding encoded multimedia content. The video processing component 1122 can aid in facilitating the generation, editing and sharing of video quotes.

In order to provide additional context for various embodiments described herein, FIG. 12 and the following discussion are intended to provide a brief, general description of a suitable computing environment 1200 in which the various embodiments of the embodiment described herein can be implemented. While the embodiments have been described above in the general context of computer-executable instructions that can run on one or more computers, those skilled in the art will recognize that the embodiments can be also implemented in combination with other program modules and/or as a combination of hardware and software.

Generally, program modules include routines, programs, components, data structures, etc., that perform particular tasks or implement particular abstract data types. Moreover, those skilled in the art will appreciate that the disclosed methods can be practiced with other computer system configurations, including single-processor or multiprocessor computer systems, minicomputers, mainframe computers, Internet of Things (IoT) devices, distributed computing systems, as well as personal computers, hand-held computing devices, microprocessor-based or programmable consumer electronics, and the like, each of which can be operatively coupled to one or more associated devices.

The illustrated embodiments of the embodiments herein can be also practiced in distributed computing environments where certain tasks are performed by remote processing devices that are linked through a communications network. In a distributed computing environment, program modules can be located in both local and remote memory storage devices.

Computing devices typically include a variety of media, which can include computer-readable storage media, machine-readable storage media, and/or communications media, which two terms are used herein differently from one another as follows. Computer-readable storage media or machine-readable storage media can be any available storage media that can be accessed by the computer and includes both volatile and nonvolatile media, removable and non-removable media. By way of example, and not limitation, computer-readable storage media or machine-readable storage media can be implemented in connection with any method or technology for storage of information such as computer-readable or machine-readable instructions, program modules, structured data or unstructured data.

Computer-readable storage media can include, but are not limited to, random access memory (RAM), read only memory (ROM), electrically erasable programmable read only memory (EEPROM), flash memory or other memory technology, compact disk read only memory (CD-ROM), digital versatile disk (DVD), Blu-ray disc (BD) or other optical disk storage, magnetic cassettes, magnetic tape, magnetic disk storage or other magnetic storage devices, solid state drives or other solid state storage devices, or other tangible and/or non-transitory media which can be used to store desired information. In this regard, the terms “tangible” or “non-transitory” herein as applied to storage, memory or computer-readable media, are to be understood to exclude only propagating transitory signals per se as modifiers and do not relinquish rights to all standard storage, memory or computer-readable media that are not only propagating transitory signals per se.

Computer-readable storage media can be accessed by one or more local or remote computing devices, e.g., via access requests, queries or other data retrieval protocols, for a variety of operations with respect to the information stored by the medium.

Communications media typically embody computer-readable instructions, data structures, program modules or other structured or unstructured data in a data signal such as a modulated data signal, e.g., a carrier wave or other transport mechanism, and includes any information delivery or transport media. The term “modulated data signal” or signals refers to a signal that has one or more of its characteristics set or changed in such a manner as to encode information in one or more signals. By way of example, and not limitation, communication media include wired media, such as a wired network or direct-wired connection, and wireless media such as acoustic, RF, infrared and other wireless media.

With reference again to FIG. 12, the example environment 1200 for implementing various embodiments of the aspects described herein includes a computer 1202, the computer 1202 including a processing unit 1204, a system memory 1206 and a system bus 1208. The system bus 1208 couples system components including, but not limited to, the system memory 1206 to the processing unit 1204. The processing unit 1204 can be any of various commercially available processors. Dual microprocessors and other multi-processor architectures can also be employed as the processing unit 1204.

The system bus 1208 can be any of several types of bus structure that can further interconnect to a memory bus (with or without a memory controller), a peripheral bus, and a local bus using any of a variety of commercially available bus architectures. The system memory 1206 includes ROM 1210 and RAM 1212. A basic input/output system (BIOS) can be stored in a non-volatile memory such as ROM, erasable programmable read only memory (EPROM), EEPROM, which BIOS contains the basic routines that help to transfer information between elements within the computer 1202, such as during startup. The RAM 1212 can also include a high-speed RAM such as static RAM for caching data.

The computer 1202 further includes an internal hard disk drive (HDD) 1214 (e.g., EIDE, SATA), one or more external storage devices 1216 (e.g., a magnetic floppy disk drive (FDD) 1216, a memory stick or flash drive reader, a memory card reader, etc.) and an optical disk drive 1220 (e.g., which can read or write from a CD-ROM disc, a DVD, a BD, etc.). While the internal HDD 1214 is illustrated as located within the computer 1202, the internal HDD 1214 can also be configured for external use in a suitable chassis (not shown). Additionally, while not shown in environment 1200, a solid state drive (SSD) could be used in addition to, or in place of, an HDD 1214. The HDD 1214, external storage device(s) 1216 and optical disk drive 1220 can be connected to the system bus 1208 by an HDD interface 1224, an external storage interface 1226 and an optical drive interface 1228, respectively. The interface 1224 for external drive implementations can include at least one or both of Universal Serial Bus (USB) and Institute of Electrical and Electronics Engineers (IEEE) 1394 interface technologies. Other external drive connection technologies are within contemplation of the embodiments described herein.

The drives and their associated computer-readable storage media provide nonvolatile storage of data, data structures, computer-executable instructions, and so forth. For the computer 1202, the drives and storage media accommodate the storage of any data in a suitable digital format. Although the description of computer-readable storage media above refers to respective types of storage devices, it should be appreciated by those skilled in the art that other types of storage media which are readable by a computer, whether presently existing or developed in the future, could also be used in the example operating environment, and further, that any such storage media can contain computer-executable instructions for performing the methods described herein.

A number of program modules can be stored in the drives and RAM 1212, including an operating system 1230, one or more application programs 1232, other program modules 1234 and program data 1236. All or portions of the operating system, applications, modules, and/or data can also be cached in the RAM 1212. The systems and methods described herein can be implemented utilizing various commercially available operating systems or combinations of operating systems.

Computer 1202 can optionally include emulation technologies. For example, a hypervisor (not shown) or other intermediary can emulate a hardware environment for operating system 1230, and the emulated hardware can optionally be different from the hardware illustrated in FIG. 12. In such an embodiment, operating system 1230 can include one virtual machine (VM) of multiple VMs hosted at computer 1202. Furthermore, operating system 1230 can provide runtime environments, such as the Java runtime environment or the .NET framework, for applications 1232. Runtime environments are consistent execution environments that allow applications 1232 to run on any operating system that includes the runtime environment. Similarly, operating system 1230 can support containers, and applications 1232 can be in the form of containers, which are lightweight, standalone, executable packages of software that include, e.g., code, runtime, system tools, system libraries and settings for an application.

Further, computer 1202 can be enable with a security module, such as a trusted processing module (TPM). For instance, with a TPM, boot components hash next in time boot components, and wait for a match of results to secured values, before loading a next boot component. This process can take place at any layer in the code execution stack of computer 1202, e.g., applied at the application execution level or at the operating system (OS) kernel level, thereby enabling security at any level of code execution.

A user can enter commands and information into the computer 1202 through one or more wired/wireless input devices, e.g., a keyboard 1238, a touch screen 1240, and a pointing device, such as a mouse 1242. Other input devices (not shown) can include a microphone, an infrared (IR) remote control, a radio frequency (RF) remote control, or other remote control, a joystick, a virtual reality controller and/or virtual reality headset, a game pad, a stylus pen, an image input device, e.g., camera(s), a gesture sensor input device, a vision movement sensor input device, an emotion or facial detection device, a biometric input device, e.g., fingerprint or iris scanner, or the like. These and other input devices are often connected to the processing unit 1204 through an input device interface 1244 that can be coupled to the system bus 1208, but can be connected by other interfaces, such as a parallel port, an IEEE 1394 serial port, a game port, a USB port, an IR interface, a BLUETOOTH® interface, etc.

A monitor 1246 or other type of display device can be also connected to the system bus 1208 via an interface, such as a video adapter 1248. In addition to the monitor 1246, a computer typically includes other peripheral output devices (not shown), such as speakers, printers, etc.

The computer 1202 can operate in a networked environment using logical connections via wired and/or wireless communications to one or more remote computers, such as a remote computer(s) 1250. The remote computer(s) 1250 can be a workstation, a server computer, a router, a personal computer, portable computer, microprocessor-based entertainment appliance, a peer device or other common network node, and typically includes many or all of the elements described relative to the computer 1202, although, for purposes of brevity, only a memory/storage device 1252 is illustrated. The logical connections depicted include wired/wireless connectivity to a local area network (LAN) 1254 and/or larger networks, e.g., a wide area network (WAN) 1256. Such LAN and WAN networking environments are commonplace in offices and companies, and facilitate enterprise-wide computer networks, such as intranets, all of which can connect to a global communications network, e.g., the Internet.

When used in a LAN networking environment, the computer 1202 can be connected to the local network 1254 through a wired and/or wireless communication network interface or adapter 1258. The adapter 1258 can facilitate wired or wireless communication to the LAN 1254, which can also include a wireless access point (AP) disposed thereon for communicating with the adapter 1258 in a wireless mode.

When used in a WAN networking environment, the computer 1202 can include a modem 1260 or can be connected to a communications server on the WAN 1256 via other means for establishing communications over the WAN 1256, such as by way of the Internet. The modem 1260, which can be internal or external and a wired or wireless device, can be connected to the system bus 1208 via the input device interface 1244. In a networked environment, program modules depicted relative to the computer 1202 or portions thereof, can be stored in the remote memory/storage device 1252. It will be appreciated that the network connections shown are example and other means of establishing a communications link between the computers can be used.

When used in either a LAN or WAN networking environment, the computer 1202 can access cloud storage systems or other network-based storage systems in addition to, or in place of, external storage devices 1216 as described above. Generally, a connection between the computer 1202 and a cloud storage system can be established over a LAN 1254 or WAN 1256 e.g., by the adapter 1258 or modem 1260, respectively. Upon connecting the computer 1202 to an associated cloud storage system, the external storage interface 1226 can, with the aid of the adapter 1258 and/or modem 1260, manage storage provided by the cloud storage system as it would other types of external storage. For instance, the external storage interface 1226 can be configured to provide access to cloud storage sources as if those sources were physically connected to the computer 1202.

The computer 1202 can be operable to communicate with any wireless devices or entities operatively disposed in wireless communication, e.g., a printer, scanner, desktop and/or portable computer, portable data assistant, communications satellite, any piece of equipment or location associated with a wirelessly detectable tag (e.g., a kiosk, news stand, store shelf, etc.), and telephone. This can include Wireless Fidelity (Wi-Fi) and BLUETOOTH® wireless technologies. Thus, the communication can be a predefined structure as with a conventional network or simply an ad hoc communication between at least two devices.

The computer is operable to communicate with any wireless devices or entities operatively disposed in wireless communication, e.g., a printer, scanner, desktop and/or portable computer, portable data assistant, communications satellite, any piece of equipment or location associated with a wirelessly detectable tag (e.g., a kiosk, news stand, restroom), and telephone. This includes at least Wi-Fi and Bluetooth™ wireless technologies. Thus, the communication can be a predefined structure as with a conventional network or simply an ad hoc communication between at least two devices.

Wi-Fi, or Wireless Fidelity, allows connection to the Internet from a couch at home, a bed in a hotel room, or a conference room at work, without wires. Wi-Fi is a wireless technology similar to that used in a cell phone that enables such devices, e.g., computers, to send and receive data indoors and out; anywhere within the range of a base station. Wi-Fi networks use radio technologies called IEEE 802.11 (a, b, g, etc.) to provide secure, reliable, fast wireless connectivity. A Wi-Fi network can be used to connect computers to each other, to the Internet, and to wired networks (which use IEEE 802.3 or Ethernet). Wi-Fi networks operate in the unlicensed 2.4 and 5 GHz radio bands, at an 11 Mbps (802.11a) or 54 Mbps (802.11b) data rate, for example, or with products that contain both bands (dual band), so the networks can provide real-world performance similar to the basic 10BaseT wired Ethernet networks used in many offices.
